Along IR 644, which military flight operations should a pilot expect?

• A. IFR training flights above 1,500 feet AGL at speeds in excess of 250 knots
• B. Visual flight rules training flights at 1,000 feet AGL
• C. IFR training flights below 1,000 feet AGL
• D. Unmanned aircraft operations only

Answer: (D)

Military Training Routes labeled IR are intended for high‑altitude IFR training by military aircraft. On these routes, you would typically expect fast, instrument flight training by manned military aircraft rather than routine civilian VFR activities. If a particular IR segment is designated as unmanned aircraft operations only, that means there is a status or restriction in effect restricting manned operations and allowing UAS activity within that corridor. The key point is to check current publications (NOTAMs and the MOR/route notes) for the exact operations active on that segment, since overnight or temporary restrictions can change what is allowed. So, in this context, the route is described as unmanned aircraft operations only, reflecting a specific current designation for that segment rather than the usual mix of manned infrared training traffic that you might expect on a standard IR route.
